Rufus Gifford, the U.S. ambassador to
Denmark, announced Saturday that he had married his partner in
Copenhagen, the country's capital city.

The couple exchanged vows at City Hall.
Denmark in 1989 became the first nation to legalize marriage for gay
and lesbian couples.

Gifford, who was elevated to his
current post in 2013, wrote on Twitter: “Today: Stephen and I get
married @ Copenhagen City Hall - 26 ys ago the site of 1st
legal gay unions in the world. Humbled and emotional.”

In a later tweet, he shared a photo of
himself and husband Stephen DeVincent, a 56-year-old veterinarian,
dressed in tuxedos and showing off their wedding bands.

“Married! In the land that created
fairy tales, we just started our own … Feeling such happiness and
gratitude,” he wrote.

Gifford, 41, is a vocal LGBT rights
advocate and is one of six openly gay U.S. ambassadors.
